Offy dual 1bbl

Rob,
There are a couple ways to go to get heat to the carb.The best is to use a Clifford 4bbl intake with water injection with the use of the heater hoses.I do not have mine hooked up,but I live in Cal where the weather is mild.I do not run a choke either.If you are in a big time hurry,then yes they can be fickle.I usually let my car idle for a few minutes and warm up before I drive it.The engine heat will then take over to warm the intake.
